SPECIFICATION forming part of Letters Patent NO. 726,807, dated April28, 1903, Application filed February 20, 1903. Serial Noel M228. (Nomodel.)

To (.tZZ whom, it may concern..-

Be it known that 1, WILLIAM WALTER, a citizen of the United States,residing at Shelton, in the county of Mason and State of Washington,have invented certain new and use-- gated surface of the strip beingadjacent to' the interior surface of the mouth of the jar,

so that when the jar is placed in the syrup or other liquid heated tothe desired degree the liquid will be allowed to passinto the jarthrough the channels formed in the corrugated strip to fill any space inthe jar above the contents thereof- It is the purpose of the inventionto specially adapt the corrugated strip to that class of jars havingrubber or other elastic packing-rings such as is used in screw-cap jarsor other jars of whatever form and construction in which the cap extendsover the mouth of the jar toseal the same after the fruit is placedtherein. a

The invention consists in the means substantially as shown in thedrawings and hereinafter described and claimed.

Figure 1 of the drawings is a sectional elevation of the upper end of apreserving-jar, showing the elastic packing-ring and corrugated stripapplied thereto, the cap being in the position it would assume previousto its being finally screwed down tight against the mouth of the jar;Fig. 2, a perspective View of the upper portion of the jar, showing theelastic packing-ring and the corrugated strip in position and the coveror top of the jar removed; Fig. 3, a detailedview, in perspective and onan enlarged scale, of the corrugated strip used in connection with theelastic packing-ring.

In the drawings, A represents the upper portion of a preserving-jar,which may be of any suitable construction and of glass or otherpreferred material and is provided with the usualscrew or other form ofcap or cover B.

In the present instance I have shown the jar with the usual neck at,having an external inclined thread I), and the flange c of the cap orcover B, having inclined grooves to engage with the flange. This is oneof many forms of preserving-jars to which my invention is applicable,and therefore I do not wish to be understood as limiting the inventionto any special form of jar so long as it has a suitable shoulder orothersupport d for the elastic packing-ring O to rest upon, which isessential to the successful use of thecorrugated strip D, and thereforeany jar having a cap or cover to rest upon the neck thereof or extendover the same and in which an elastic packing-ring may be used isapplicable to the successful employment of the corrugated strip inconnection therewith.

The corrugated strip D may be of metal or any other suitable materialfound most desirable, said strip being of a length substantially equalto twice the Width of the elastic packing O, and after the ring isplaced upon'the shoulder or support 61 the strip rests thereon with itschanneled or corrugated surface uppermost, as shown in Fig. 2 of thedrawings.

When the jar is filled with fruit or whatever the jar is to contain, theelastic packingring is placed upon the shoulder or support, and then isplaced the cap or cover over the neck of the jar with the lower edge ofthe flange in close proximity to the elastic pack- 'ing-ring. The cap orcover is now slightly raised and the corrugated strip is placed on theelasticpacking-ring between it and the lower edge of the cap or cover ofthe jar, as shown in Fig. l of the drawings, after which only to holdthe corrugated strip in place. The jar is now submerged in a receptacleof hotwater or syrup of the required temperature or other liquid used inpreserving, and after the water or other liquid is cooled off thecorrugated strip is pulled out with finger and thumb or otherwise whileunder the water, the jar being then removed and the cap or cover tightlyscrewed down against the packing. As fast as any space is prethe cap orcover is slightly turned, sufficient sented in the jar by thecontraction or shrinkage of the fruit or other contents of the jar thewater or other liquid will find access to such space in the jar throughthe channels formed by the corrugations in the strip, and therefore thewater will rush in to fill up the space, and thus prevent anypossibility of a vacuum being formed, thereby insuring a perfectcondition of the fruit contained in the jar no matter of how longstanding.

Having now fully described myinvention, what I claim as new, and desireto secure by Letters Patent, is

1. Means for the admission of liquid to closed preserving-jars,consisting of an elastic packing and a corrugated strip placed thereonbetween said packing and the cap or cover of the jar, substantially asand for the purpose set forth.

2. The combination with a suitable jar and a cap or cover therefor, ofan elastic packing and a corrugated strip resting upon the packing andbetween it and the cap or cover and adapted for removal, substantiallyas and for the purpose described.

In testimony whereof I affix my signature in presence-of two witnesses.

WILLIAM WALTER.
